Wenlei, The power flow routine in MATPOWER does not enforce generation limits on real power. Exceeding the capacity does not necessarily imply a divergence of the power flow.

To my surprise, power flow still converges. More specifically, the total generator ‘on-line capacity’ is 820MW, while the ‘actual generation’ is 920.8MW Why the actual generation can be larger than its capacity? Blessings, Wenlei
